Questions & answers
What does Compost Mix Volume Planner calculate?
Divide a target compost mix by a volume ratio you supply.
Which units should I enter?
Total volume uses liters. Brown material parts uses parts. Green material parts uses parts. Convert values to these units before calculating.
Which formula does it use?
Each volume = total × material parts/sum of parts; this is not a carbon-to-nitrogen analysis.
What does the included example show?
Total volume: 100 liters; Brown material parts: 3 parts; Green material parts: 1 parts. Result: Brown material · liters = 75; Green material · liters = 25.
Can I compare different settings?
Yes. Save a scenario, change the inputs and save another result. Up to five scenarios are compared in this tab; they disappear when you reload or leave.
Can I export the calculation?
Copy the JSON report or download JSON and CSV with inputs, result labels and numeric values. Processing uses local JavaScript; no calculation request is sent to our server. Displayed values use up to 10 significant digits; exports retain JavaScript numeric precision.
